Abstract
Quantification of complex cellular morphology is important for understanding developmental control of cell shape as well as the developmental ramifications of dysregulated cell shape. However, processing and scoring 3D confocal micrographs can be time consuming and prone to errors such as sample-data matching for large datasets, reproducibility between users, and errors introduced by variable image quality. These problems are further compounded where cell shapes vary from sample to sample and intensity dynamic ranges extend over orders of magnitude. Here we present a package of ImageJ macros we developed for analysis of the C. elegans hermaphrodite distal tip cell (DTC) to (a) optimize images for analysis and (b) assist in quantifying various features of the cell by two independent methods, one user-guided and the other unbiased. Together these tools provide functionality for visualization and multiple parameters of quantification which can be easily customized within free open-source ImageJ.
